Question

Which of the following is true of a genetic disease caused by a gene described as autosomal recessive?

1. Males and females inherit them in equal numbers

2. An individual must get two recessive alleles to have the disease

3. The disease must be carried in both families of the pedigree that produced the child with the disease.

4. All of the choices are correct

Answer 1

the Correct option is -

4. All of the choice are correct

• If the gene is not sex linked then the gender bias will not take place and the disease will effect both male and female.
• The autosomal recessive disease will only occur when the two alleles of the resonsible gene is recessive (mutated). One dominant gene (heterozygous) will nullify the chance of disease
• the third point is also true. Parents must be carrier in this case. If one of the parent is Not carrier ( homozygous dominant) then the disease will not arise in the offspring altough the offspring may be carrier.
